Eastman 12" Frost-Free Sillcock Outdoor Brass Spigot with Vacuum Breaker, 1/2" MIP x 1/2" Sweat, 125 PSI

Eastman's 12-inch frost-free sillcock is a heavy-duty brass outdoor spigot with a built-in vacuum breaker that prevents backflow and keeps the line clear in freezing conditions.

This 12" frost-free sillcock from Eastman combines durable brass construction with a vacuum-breaker design to protect potable water and resist corrosion. Designed for exterior walls, its long stem keeps the valve mechanism inside a heated area, reducing the chance of freeze damage. The unit is sized 1/2" MIP x 1/2" sweat for straightforward connection to standard plumbing and includes a notched flange and large wheel handle for fast, dependable installation and operation.

How does this sillcock protect my plumbing in winter?

The extended 12-inch stem locates the valve seat deeper inside the building envelope, so the water drains away from the outdoor opening when shut off. The frost-proof layout helps prevent trapped water from freezing inside the valve body. Additionally, the robust brass body resists cracking and corrosion in cold, wet conditions.

• 12" stem keeps valve seat inside heated space
• Drains water away from exterior wall when closed
• Brass construction resists corrosion and cold damage
• Rated to 125 PSI and 160°F for typical residential use

What does the vacuum breaker do and why does it matter?

The integrated vacuum breaker prevents backflow by allowing air into the line when a siphon might form, stopping contaminated water from being drawn back into your potable supply. It’s a simple passive safeguard that meets common plumbing backflow-prevention needs without separate devices. This helps maintain water quality at outdoor spigots used for irrigation, washing, or filling containers.

• Prevents siphoning and backflow into house plumbing
• Built into the sillcock — no separate backflow valve required
• Useful for hoses, sprinklers, and outdoor water use

How easy is installation and what fittings are required?

Eastman designed the sillcock for straightforward mounting: the notched flange aligns with siding for a stable exterior seal, and the 1/2" MIP x 1/2" sweat connections match common supply lines. The large wheel handle makes the valve easy to operate while you complete connections. For sweat installation, you’ll solder the 1/2" sweat end to copper, while the 1/2" MIP threads accept standard female-threaded fittings or adapters.

• Notched flange for secure siding installation
• 1/2" MIP x 1/2" sweat connection—works with copper and threaded fittings
• Large wheel handle for simple shutoff and control
• Compatible with common residential plumbing practices

What are the durability and performance specifications?

Constructed from heavy-duty brass, this sillcock resists rust and deformation over time. It’s rated for a maximum working pressure of 125 PSI and maximum temperature up to 160°F, making it suitable for outdoor faucets, garden hose connections, and general exterior water service. The hardware and finish are selected to stand up to the elements without frequent replacement.

• Heavy-duty brass body for long-lasting performance
• Maximum pressure: 125 PSI; maximum temperature: 160°F
• Large wheel handle and robust stem for reliable operation

Who is this for: Homeowners, contractors, and renovators who need a reliable exterior faucet that reduces freezing risk and protects potable water will find this Eastman frost-free sillcock well suited to the task. It fits common 1/2" copper or threaded supply lines, installs cleanly against siding, and is a good choice for replacing older sillcocks or specifying durable outdoor spigots on new construction projects.
